kow [346]

Answer:

love of water

Explanation:

HYDROPHILIC is a term used for substances that are WATER-LOVING in nature. As the name implies, hydro-meaning water and philia- meaning love, it means the love of water. Substances that are hydrophilic tend to be attracted towards water molecules and are readily dissolved by it. For example, sugar molecules are hydrophilic, hence, attract and dissolve in water.

On the other hand, hydrophobic means water-fearing i.e substances under this category repel water. Examples are some fat molecules.
